I l To all whom may concern:

Be it known that I, Trnionoiiii MARSHALL Fours, a citi'z'en `of the United Stu-tes, and a resident of Allston, in the county of Suffolk and State of Massachusetts, (whose postoice address fis Allston, Massachusetts.) have inventedfan Improvement in Auto` matic LabelingMachines, of which the following descrption, in connection with the Zaccoiripanyiiilg drawings, is a specification,

iks letters onthc drawings representing like arts. I The object?" f the present invention is to provide a practicable-label serving machine 1'5 which will autlimatically feed and cut labels uniform length.- Devices hitherto used for ithis purpose have been unsuccessful because l they were not adapted to automatically cut tlie printed stripat the proper places topi'of` v2, fdiice an entire-label at each cut. It is obvi @ons that a comparatively slight variation in fthe length of t e portion severed will cause i* fthe knife to cut through the printed matter lof the labels, instead of at each end thereof.

This not only wastes labels but necessitates "frequent-ly stopping the machine to readj ust the feed.

The present invention obviates `the difficulties heretofore experienced in the art by providing 'a machine in which the cutting mechanism, the feeding mechanism, and the strip of labels to be served are so related that the cutting mechanism can operate only at definite and constant intervals upon the strip regardless --of variation in the rapidity of feeding.

One form of device for accomplishing this result is illustrated in the drawings, of which, n

Figure lis a plan view showing a perforated strip operativel threaded in the machine, Fig. 2, is an elevationshowing thlniife operating and strip feeding mechanism, Fig. 3, an elevation showing a strip threaded in the machine, a mctor"f0r operating strip feeding'inecha'nism,I feedv and inoistening rolls in section, and au electrical circuit diagrammatically, and, .Fi 4, a detail view 1n section on line 4-4 of ig. 2, of the mecha-- nism by whichrtheknife is made tooperate. A strip a having perforations b is mounted as shown in Figs. 2 and 3, so as to be drawn from a roll c by means of feed rollers d,

, thence over a moistening roller e to a posib5 tion for severance by a knife f. Between the Specification of Letters Patent. Application tiled April 15,1913. Serial No. 761,175.

roll c and the knife f the'strip asses acros'sa contact g in :in electrical circuit li, which incliides also an induction coil and magnet j, an armature It, and an adjustable brush l to closetlie' circuit with the contact gtlius mag-` Iietizing the magnet j. A motor n? furnishes power to drive a shaft o which in turn drives the feed rollers d and the vmoistening rolll through suitable intermediatefgears. 'l' A d isk p loosely mounted upon theshaft `o is equipped on one side with ya pivoted spring latch i' adapted to engage aratchet wheel sfixed upon the shaft o.` On the other side of the disk is u crank pin t adapted to engagea slot i) in a lever arm a: pivotally mounted at y. The armature lc is pivotally mounted at a with a projecting arm m'spring held in. normal engagement with the latch r.

Inl operation, the feed rollersd drawout thestrip at a suitable speed' across the conf.- 75 tact plate gas previously described. During this operation, the circuit h remains 'open except when one of the'perforations registers with the brush l. This closes the circuit-ebd causes the armature [c to be attracted tothe iniignet j, thus releasin the latch-'r` whil A immediately engages t e ratchet .wheel 73:... '1 he disk D then rotates withithe shaft o, u cting upon the lever arm ai to operate thel knife f by iiieans of the crank in t. l'Vhen 85 the lii tcli returns to its norma position, it ogaingcncounters the projecting arm m ofthe armature le, which has meanwhile been releasedj fr0m the magnet upon break of the clrciiit by interposition of the wd offgo the strip, and is thereby released from engagemcnt with the ratchet 'wheel s.

The brush Z is adjustably mounted with relation to the contact iiioorde'r t0 provide L handling of labels of diieientlengths, it

being obvious that the distance' from the knife to the point of contact must bear some fixed proportion to the length '.of the label., That is, 1f the -perforations occurbetween each two labels, the knife must be at least 10|) `the length of oiic'label from the perforation through which the circuit is being closed; or any suitable multiple thereof. This distance having been carefully ascertained 'for' any given strip of labels, it will be seen that the knife will always cut a label of the required length regardless of any variation-in the` speed of the feed rollers.

The foregoing description has to do with a device in which the circuit isnornially open.
